' APPARA'I'US FOR REPAIRING MOTION -PIGTURE FILMS.

To all whom it may concern:

Be it known that I, EDMUND M. BENDI-IIEIM, a citizen of the United States, and a resident of New York city, in the county and State of New York, have invented certain new and useful Improvements in Apparatus for Remanipulated, and insures such a correct concutter head thrown back. Fig.

nection between the film sections, that the apertures of the entire length of the restored film will register truly with the pins of the camera film feeding device. v

In the accompanying drawing: Figure 1 is a plan of a film repairing apparatus embodying my invention, with the clgmps alnd a p an showing the cutter head thrown back and the clamp closed. Fig. 3 is a longltudlnal. section on line 3-3 Fig. 2; Fig. 4, a cross section on line 4+4: Fig.3; Fig. 5,-a cross table 1 there section on line 5-'5 Fig. 3; Fig. 6, a cross. section on line 66 Fig. 3; Fig. 7 shows a portion of .the film after being cut; Fig. 8 shows a portion of the film with the severed piece removed, and the flap scraped and Fig. 9, shows the film after being repa1red. The apparatus comprises essentlally, a fixed table or base plate 1 shown to be mounted on a depending rim 2, and adapted to support a portion of a film 3 to be repaired. From preferably the left portion of project upwardly, two rows of fixed pins 4 registering with the apertures 5 of film 3, while the right portion of table 1, is provided with two corresponding rows of pins 6, which may either be pro ected above the surface of the table or sunk below the same. These vertically movable or disappearing pins are secured to a plate 7, arranged below table 1 and turning on a hinge 8. The plate may be raised by means of a cam 9, mounted on a shaft 10 which may be turned by a knob 11, so that in this way the Specification of Ietters Patent.

pins 6 are projected upward through corresponding apertures of table 1. When shaftv 10 is turned in an opposite direction, plate 7 1s lowered by means of a spring 12, so that the pins will be sunk beneath the surface of the table. To one of the longitudinal edges of table 1, there is hinged, a first clamp 13, a cutter head 14, and a second clamp 15, all arranged in proximity to each other, and adapted to be either thrown back, or to be folded over the table. The cutter head 14, which is flanked by the clamps 13, 15 is pref erably so constructed, that a true vertical movement will be imparted to the same, during the cutting operation. To this efi'ect, 1t is shown to be pivoted at one end to a plunger 16- mounted on a spring 17 and guided within a socket 18 of table 1, the movement of the plunger being restricted by a pin and slot 19. At its other end, the cutter head is provided with a plunger-20, fitted within a socket of the cutter head and influenced by a spring 21, the play of the plunger being defined by a pin and slot connection 22. To each face of head 14 is adapted to be attached a cutting blade 23 having preferably outwardly curved ends, and provided with a slot 24: fitting over corresponding studs 25 of head 14, the blade after being fitted in position, being secured to the head by means of a clamp screw 26. It will be seen that when the cutter head is folded over the table 1, and pressure is ap plied thereto, the head will be forced vertically downward, so that the knives 23 will squarely cut across thefilm,with a uniform action throughout their length, the knife Patented Aug. 22, rare. I

edges being received within correspondingly 13 is provided with a longitudinal groove 30 adapted for the reception body of the film. At its up of a slide 31, which is movable upon a ball race 32. From slide 31 extends sidewise an arm 33 to which a scraping tool 34 is secured by a set screw 35. Head 14 is so spaced from clamp 13, that tool 34 is adapted to reciprocate across the film, directly beyond the stroke-plane of the left hand cutter 23. The

clamp may be locked to the table by means,

of a suitable catch 36.

To the right of cutter head 14, there is pivoted to the table, the clamp 15, which may thus be projected over the innermost of the movable pins 6, said clamp being similar to clamp 13, provided with a pair of film receiving transverse bottom grooves 37, a lower pad 38 and a catch 39. To the inner edge of clamp 15, there is hinged at 40, a presser foot 41 which is of such a length, that when swung downward, it will closely approach clamp 13. The presser foot may be forced downward by means of a spring blade 42, pivoted to clamp 15, at 43, and adapted to be swung over presser foot 41 by means of a handle 44.

The operation is as follows: The clamps 13, 15 and cutter head 14 are swung back, (Fig. 1), pins 6 are raised, and the film to be repaired is so fitted upon the pins, that its mutilated portion faces a pointer 46 marked on table 1, within the sweep of cutter head 14. The clamps are thrown across the table and secured by catches 36, 39 to hold the film in place. That portion of the film located between clamp 13 and cutter head 14 is wetted, and the slide 31 is reciprocated so that scraper 34 will remove the emulsion therefrom. The cutter head is swung forward and is depressed, so as to sever the damaged film section which is discarded after the cutter head has been again swung back. Cement is applied to the scraped portion of the film as indicated at 47 Fig. 8. (In order to permit a free movement of the scraper over the rim, the pins 4 are here omitted). Pins 6 are depressed, the right section of the film is advanced to overlie with its left end or rim, the prepared right rim of the left section, while its extreme left apertures will become engaged by the extreme right fixed pins 4. The presser foot 41 is thrown down, and forced against the superposed rims by the spring blade 42 which is swung over the same. :WVhen the film sections have become thoroughly united. the clamps are swung up, and the film which has thus been properly rep. lred is removed.

I will be seen that with my apparatus the film can be repaired in a quick and neat manner, and that in the film thus repaired, the correct spacing between the apertures of the united sections will be maintained, so that the film may subsequently be engaged in proper manner by the feeding mechanism of the camera.
